  2. CONTENT • Introduction React JS and JSX • Component, State, Props. • Life Cycle of Component • Pros & Cos • Demonstration

  3. WHAT IS REACT? • A JavaScript Library For Building User Interfaces • Renders your UI and responds to events. • It also uses the concept called Virtual DOM, creates an in-memory data structure cache, enumerates the resulting differences, and then updates the browser’s displayed DOM efficiently. • One of the unique features of React.js is not only it can perform on the client side, but it can also be rendered on the server side, and they can work together interoperably.

  4. WHAT IS REACT? • modules • controllers • directives • scopes • templating • linking functions • filters • dependency injection

  5. COMPONENT • Components let you split the UI into independent, reusable pieces, and think about each piece in isolation. • Conceptually, components are like JavaScript functions. They accept arbitrary inputs (called "props") and return React elements describing what should appear on the screen.

  6. COMPONENT - PROPS • Props is what you pass into the Component via attributes. • Props is the only way to input data. (Or you can use Redux). • Props are immutable. • Container component will define data that can be changed • Child Component will received data from parent component via props.

  7. COMPONENT - STATE • Private data of component • When change -> Re-render Component • Can’t read from outside Component

  8. REACT COMPONENT LIFECYCLE • React enables to create components by invoking the React.createClass() method which expects a render method and triggers a lifecycle that can be hooked into via a number of so called lifecycle methods. • This short article should shed light into all the applicable functions. • Understanding the component lifecycle will enable you to perform certain actions when a component is created or destroyed. Further more it gives you the opportunity to decide if a component should be updated in the first place and to react to props or state changes accordingly.

  9. PROS & COS OF REACT.JS THE GOOD POINTS THE BAD • React.js is only a view layer. • There is a learning curve for beginners who are new to web development. • Library size. (~ Angular) • React.js is extremely efficient - Virtual DOM • It makes writing Javascript easier - React.js uses a special syntax called JSX • It gives you out-of-the-box developer tools - React.js chrome extension • It’s awesome for SEO - Server rendering • UI Test Cases

  10. Why Reactjs: use • React.js works great for teams, strongly enforcing UI and workflow patterns. • The user interface code is readable and maintainable. • Componentized UI is the future of web development, and you need to start doing it now. • And also, there is now a lot of demand for developers with ReactJS experience. NOT USE • Slow you down tremendously at the start. • You will reinvent a lot of wheels.
